Siemens 3RT2924-5AG21 Magnetic Coil 110V AC, Compatible with 3RT202 Contactors Original Brand New

Overview: Siemens 3RT2924-5AG21 Magnetic Coil

The Siemens 3RT2924-5AG21 is a high-quality, genuine replacement magnetic coil designed specifically for the popular SIRIUS 3RT2 series of power contactors. It provides the reliable, climate-proof control mechanism necessary for the contactor’s operation.

This specific coil operates with a standard 110 V AC control supply voltage at both 50 Hz and 60 Hz frequencies, making it suitable for a wide range of global industrial and commercial applications. It is sized perfectly as an accessory for Size S0 contactors.

Compatibility & Function

• Product Number: 3RT2924-5AG21
• Accessory Type: Magnet Coil / Solenoid Coil / Replacement Coil
• Control Voltage: 110 V AC, 50/60 Hz
• Contactor Compatibility: Designed for use with SIRIUS 3RT2 power contactors in the Size S0 frame:
  • 3RT2023-**.A (e.g., 3RT2023-1A.0)
  • 3RT2024-**.A (e.g., 3RT2024-1A.0)
  • 3RT2025-**.A (e.g., 3RT2025-1A.0)
